How to use the fitting chart
If you know your bra size. skip to step 4. If you do not know your bra band size, take a measurement going all the way around your body beneath the curve of your pectoral muscle.
Example: Measurement is 35 inches
Follow this measurement to determine your bra band size (what your body says you are)
Example: Bra band is 40
Decide which cup size you would like to be.
Example: C cup for proportional shape
Intersect your bra band size with the cup size you want to be. The number in the intersecting row and column will be the size to order!
Example: 40C is a size 6

Helpful tip for ordering breast forms
Do not attach your breast forms to your body until you know that you love them! Only attach them once you are sure of your sizing. Once they have been attached to the body in any way, they cannot be returned or exchanged.

Warranty information
All Platinum Seal, Gold Seal, and Silver Seal traditional breast forms are guaranteed against manufacturers defects for one year from date of purchase.
Platinum Seal, Gold Seal, and Silver Seal traditional breast forms are guaranteed against failure of the double-strength membrane on the back side of the forms caused by double-sided adhesive tapes manufactured for and sold by The Breast Form Store and its affiliates. Skin Tac Wipes and Holdup adhesive are also covered in this guarantee, however the use of any other tape or attachment method will void the guarantee.
Platinum Seal, Gold Seal, and Silver Seal traditional breast forms are not guaranteed against abuse, punctures by sharp objects, excessive pressure being placed on them, excessive heat, or other actions that would not be consistent with normal wearing of a breast prosthesis.
Warranty claims
All claims under this guarantee require the return of the breast forms to The Breast Form Store. Breast forms cannot be returned without a Return Authorization Number. Please contact us for an authorization number. Shipping charges are at the expense of the buyer. The guarantee only extends to the initial pair of breast forms purchased and not to any replacement forms.
Adhesive use warning
While many of our clients are using other adhesives, sprays, tapes and removers with success, we regret that we cannot provide a warrantee if they are used. There are so many formulations of adhesives and removers that that The Breast Form Store is unable to test and guarantee them all. Some of them may cause damage to the breast form if used.
If you are considering any other method of attaching the breast forms than the products we provide, please do so with caution.
A very safe and easy adhesive remover is baby oil. It is safe to use with most liquid adhesives and double-sided tapes, as that baby oil neutralizes most adhesives. Apply to edges of tapes and slowly remove tapes as adhesive is neutralized. You will not be able to re-use the adhesive if it is removed with baby oil.
